English
This paper presents a novel fully electrified CO2 loop integrating direct air capture (DAC) with plasma-based calcination. Atmospheric CO2 is captured via alkaline absorption, solidified as CaCO3, then decomposed by rotating gliding arc plasma to regenerate CaO and produce CO for syngas. High-purity Ca products are confirmed, offering a pathway to decarbonize cement and transport sectors.

📄 Abstract（原文）
The persistent reliance of the cement sector on fossil fuels for CaO production and the high energy demand for DAC sorbent regeneration pose a significant barrier to reaching sustainable industrial production. Herein, a novel process concept is presented, establishing an integrated, fully electrified CO2${\rm CO}_2$ ‐loop driven by gliding arc plasma technology. Atmospheric CO2${\rm CO}_2$ is captured in an alkaline absorption unit, where the pH value serves as a reliable performance parameter for system predictability. Subsequent liquid‐solid conversion solidifies the captured CO2${\rm CO}_2$ as CaCO3${\rm CaCO}_3$ , achieving a high yield with high phase purity. Rotating gliding arc plasma experiments successfully demonstrate the electric calcination for CaO regeneration and the CO2${\rm CO}_2$ release to close the carbon and calcium loop. With the ability of simultaneous plasma‐based CO2${\rm CO}_2$ splitting the process enables the use of the resulting CO as a precursor for synthesis gas. The observation of internal temperature gradients facilitates the definition of a suitable reaction volume for calcination. XRD and TGA/DSC analyses confirm the formation of pure Ca‐products, validating the concept. This work provides a foundational material‐flow validation for this novel DAC Power‐to‐X pathway, substituting fossil fuels for calcination and DAC‐operation entirely with electrical energy. The process offers a crucial opportunity for the decarbonization of the construction and transport sectors, with future work focusing on optimizing reactor design for continuous operation.
